Non-comparative Study of BCD-085 in Combination With UDCA in Patients With Primary Biliary Cholangitis

Phase 2

Terminated

• Conditions: Liver Cirrhosis, Biliary
• Interventions: Biological: BCD-085

• Registration Number: NCT03476993
• Lead Sponsor: Biocad

Brief Summary

BCD-085 is an innovative drug, anti-interleukin-17 monoclonal antibody. The aim of the study is to evaluate the efficacy and safety of BCD-085 in patients with primary biliary cholangitis (PBC).

Detailed Description

This is an open-label proof-of-concept phase 2A study. The aim of the study is to evaluate the efficacy and safety of BCD-085 in combination with ursodeoxycholic acid in patients with primary biliary cholangitis (PBC) with compensated liver function with an inadequate (suboptimal) response to ursodeoxycholic acid.

In this study the inadequate (suboptimal) response to ursodeoxycholic acid (UDCA) is defined as screening alkaline phosphatase (ALP) level \> 1.67 ULN (the upper limit of normal) despite treatment with UDCA in stable dose for at least 6 months before signing the ICF.

• Sex: All
• Target Recruitment: 9

Inclusion Criteria

1. Singed informed consent form (ICF)

2. Men and women, age 18 - 80 years at the time of signing the ICF

3. Established diagnosis of PBC with following criteria (according to EASL 2017 guidelines):

   • documented ALP elevation
   • documented АМА ≥ 1:40 or PBC-specific ANА (anti-sp100/anti-gp210).

4. Suboptimal response to ursodeoxycholic acid (UDCA) taken in stable dose for at least 6 months before signing ICF with screening alkaline phosphatase (ALP) level > 1.67 ULN (the upper limit of normal)

5. Fertile patients and their partners agree to use barrier contraception throughout the study and 4 weeks after its completion.

Exclusion Criteria

1. History of gastrointestinal bleeding, hepatic encephalopathy or ascites requiring treatment with diuretics.
2. MELD ≥ 15, history of liver transplantation, staying in the Liver Transplant Waiting List.
3. Established diagnosis of hepatocellular carcinoma (HCC), hepatorenal syndrome.
4. Direct bilirubin > 1.0 mg/dL at screening.
5. Documented diagnosis: nonalcoholic steatohepatitis, autoimmune hepatitis, primary sclerosing cholangitis, alcoholic liver disease, Gilbert's syndrome, Wilson disease, hemochromatosis, alfa-1-antitrypsin deficiency.
6. HIV, hepatitis B, hepatitis C or syphilis.
7. Use of colchicine, methotrexate, azathioprine or systemic corticosteroids within 3 months before signing the ICF.
8. Previous use of monoclonal antibodies targeting IL17 or its receptor.
9. Vaccination with live or attenuated vaccines within 8 weeks before signing the ICF.
10. Any active systemic infection or recurrent infection at screening or 30 days before signing the ICF.
11. Established diagnosis of chronic disease (e.g. sepsis, invasive mycosis, histoplasmosis etc.) that may increase the risk of infectious adverse events during the study.
12. Severe infections (including those that required hospitalization or parenteral antibacterial/antimycotic/antiprotozoal treatment) within 6 months before signing the ICF
13. Established diagnosis of herpes zoster infection (or history of herpes zoster infection).
14. latent tuberculosis infection (positive results of the Diaskintest or QuantiFERON test, or T-spot).
15. Concurrent diseases at screening that may increase the risk of adverse events during the study or affect the evaluation of PBC symptoms (mask, enhance or alter the symptoms of PBC, or cause clinical or laboratory signs/symptoms similar to those of PBC)
16. Known allergy or intolerance to monoclonal antibody drugs (murine, chimeric, humanized, or human) or any other components of BCD-085.
17. Pregnancy, breastfeeding or planning of pregnancy during the study.
18. Any psychiatric conditions including severe depressive disorders and/or any history of suicidal thoughts or suicidal attempts that may constitute the excessive risk for the patient or that may affect the patient's ability to follow the protocol.
19. Alcohol or substance abuse.
20. Participation in other clinical trials within less than 90 days before signing the ICF.
